Iterating through the classes 'Point '...

Hello world

I have a question very very simple to ask:
The following lines are inside one of my methods:


Focus() dim = new Point [5];

for (int i = 0; i < 5; i ++) {}
protected.x = (int) (Math.Random () * 100);
Var [i] there = (int) (Math.Random () * 100);
}


and for some reason, I get a null pointer exception error!

Any help... ?

Exactly! It goes the same for your situation. Creating a table does not automatically create objects and insert them for you.

PS how do you set the code tags?

Type

  • Tunnel traffic through the Access Point

    I "tunnelenabled" in the parameters of Access Points of JSON: true;

    And on the Access Point associated connection servers config guide recommends not allowing the tunneling.

    The end result is that the traffic is going through the Access Point and not crossing does not connect to the server. The client wants to keep the absolute minimum for the ports open between the objects, so I want to tunnel traffic from the Access Points through the connection to the server, and then click the virtual and physical machines internal who installed the agent to view. Even when I check the options of tunnel on the login server it always appears as if traffic is bypassing the broker for the connections and go straight to the agents.


    What the configuration change that I do have all the traffic goes through the access points and associated connection servers?


    Thanks in advance for any help or suggestion-

    After a lot of trial and error reduced us to certificates that we created for Access Points. HTML5 Blast Bridge did not have other names of the object in the cert. Once we gave them a cert that had the URL and not the SAN (subject alternative names) with the real access Point server names that Blast started working again.

  • Iteration through the activeDocument.layers is very slow

    Hello

    I am trying to build a table of all visible layers currently in a document, and the only way I know how to do it is by performing an iteration (by using where loop method) app.activeDocument.layers however, the problem is it is really slow for some reason any. For 37 layers, it will sit there for about 10 to 15 seconds and the mouse pointer will fluctuate between normal and busy pointer.

    A few questions:

    (a) is there a better way to build the list of visible layers?

    (b) why it takes so long to complete this (Note: there is only a single action in the loop that is assigning the active layer in the layers panel to l):

    var layers = app.activeDocument.layers;

    for (var i = 0; i < layers.length; i ++)

    {

    var l = layers [i];

    }


    ?

    Any help on this will be appreciated!

    Thank you

    Nate

    If you have CS4, you can use the function below to get the index of the selected layers AM.

    function getSelectedLayersIdx(){
         var selectedLayers = new Array;
         var ref = new ActionReference();
         ref.putEnumerated( charIDToTypeID('Dcmn'), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') );
         var desc = executeActionGet(ref);
         if( desc.hasKey( stringIDToTypeID( 'targetLayers' ) ) ){
              desc = desc.getList( stringIDToTypeID( 'targetLayers' ));
              var c = desc.count
              var selectedLayers = new Array();
              for(var i=0;i
    

    There isn't really any documentation by using the Action Manager. The javascript guide that ships with Photoshop lists the properties and methods for the action descriptor, Action reference and list of actions. And the app.object methods to convert an ID.

  • to access the pots through the class-path to the manifest of a shared library.

    I have a large number of pots that are used by the J2EE applications and stand-alone (client) applications.

    I like to keep only one copy pots on the drive (for example, in a myLibraries/lib directory).

    Is there a way I can create a shared library with the Class-Path entry in a manifest that points to the jar files in the myLibraries/lib directory? (If Yes, which? the ear of shared library manifest, the manifest of a pot of "module" in the ear of shared library or the manifest of a pot within the APP-INF/lib?)

    Otherwise, it seems that I have to include copies of these pots in the EAR of my shared library application.

    Thanks in advance
    Mike

    Mike,

    I guess that it may be possible to refer to the pots where they are already using a manifest, but this isn't how I saw. If you look at weblogic.jar, it's META-INF/manfiest.mf uses references to other module pots. However, you're talking as if you want to do something more absolute path. Why not consider the following which is more standard...

    To use a pot as a shared library or optional package, study it:
    http://download.Oracle.com/docs/CD/E14571_01/Web.1111/e13706/libraries.htm#i1070930

    Basically, make sure that the jars you want to be a shared library have a manifest file which specifies the extension name, spec, and version impl.

    For example. Let's say you have myExtension.jar - inside there should be a META-INF/MANIFEST. File MF that looks like this:
    Name of the extension: myExtension
    Specification-Version: 2.0
    Implementation-Version: 9.0.0

    Deploy this jar in a WLS library.

    Second, depending on which classloader you want to access in the container, make a reference to the optional package. For example, in the EAR that you want to access this pot, change META-INF/MANIFEST the EAR. MF so that it looks like this:
    List of extensions: myExtension
    myExtension-Extension-name: myExtension
    myExtension-Specification-Version: 2.9
    myExtension-application-Version: 9.0.0

    You can also reference the style jar libraries in weblogic application. The EAR like this XML:

    ...

    myExtension

    ...

    Note that the library-ref above referring to a jar approach does not work for applications packaged as WAR files and editing weblogic.xml, you must use the obvious approach for the web module archive jar base shared libraries reference.

  • Incrementing counter on stage through the class

    Hello everyone, I have a thread similar to this on the saving and loading of a meter. However, I can not get the counter increment when colliding with an object. When the collision with the object, it makes not visible so that you can not see more.

    My meter that records and load looks like this:

    var so: SharedObject = SharedObject.getLocal("myStuff","/");

    var JumpCounter: int = 0;

    If (SO. Data.JumpCounter)

    {

    JumpCounter = so.data.JumpCounter;

    }

    And when you jump:

    JumpCounter ++;

    so.data.JumpCounter = JumpCounter;

    so. Flush();

    It outputs here in a text box:

    JumpBox.text = JumpCounter.toString ();

    This set works very well, I just can't get it to increment when colliding with my MovieClip.

    I have a class that looks like this attached to my MovieClip I want to increment which looks like this:

    package {}

    import flash.display. *;

    import flash.events. *;

    SerializableAttribute public class AddJumps extends MovieClip {}

    build function

    public void AddJumps (): void

    {

    addEventListener (Event.ENTER_FRAME, collision);

    }

    private void collision(e:Event):void {}

    If (this.hitTestObject (MovieClip (root). (Player)) {}

    MovieClip (root). JumpIcon.visible = false;

    }

    }

    }

    }

    I'm not sure access to the or increment my counter to a category. I can't remember how to access the scene.

    Thanks in advance!

    It's the only part that you add to your class:

    MovieClip (root) .incrementJumpCounterF ();

  • How well the class prepare you for the exam?

    I'm looking at planning for the installation of VCP5 set up class (not the fast track one).  I have given the task up VMWare ESXi and run for my group.  I will do this on Cisco UCS.  Even if the Cisco class is supposed to help me get started on getting installed ESXi, I plan to pay on my own to go to VMware installation you configure class.  What concerns me, it is the class getting ready to review?  I got several Cisco certificates over the years and have found that classes don't really help you with what is perhaps reviews, as a writing group at Cisco exams and one other group wrote material for classes.

    I would like to hear from those who have gone through the classes for your printing.  I am watching 3 third-party sources for other material that would help me as well as establishing a "lab" server using vm workstation or fusion and ESXi running on this.

    Thank you

    Ron

    The class teaches you the product so it will obviously help, but the objectives of the training are only a partial match to review.

    You can compare the objectives of training compared to the objectives of the review by downloading the form of training and the examination plan.

    There is lots of useful information and links on my blog, including links to some practical examinations - click on the VCP5 tab.

    Regarding the labs, I would look at Autolab and build the ultimate vSphere lab.

  • Access the class from the loaded module

    I have this in the main application and I the public variable test in the module. The problem is that I don't know how to access it properly.

    public

    var fontsModule:IModuleInfo;

    public var FontsClass: Class;

    public

    function initApp(evt:FlexEvent):Sub

    {

    fontsModule = ModuleManager.getModule ("modules/fontsBG.swf");

    fontsModule.addEventListener (ModuleEvent.READY, fontsLoaded);

    () fontsModule.load

    new ApplicationDomain (ApplicationDomain.currentDomain), null , null , moduleFactory);

    }

    public function fontsLoaded(evt:ModuleEvent):Sub

    {

    FontsClass = fontsModule.factory.create)

    as Class;

              trace ()' HERE: "(+ FontsClass.test);". "

    }

    If I replace the class with the name of the 'FontsBG' class actions script in this example, everything would work, but the main swf file size goes from 100 to nearly 400 kbs when the fontsBG.swf file is 67 kbs. So I'm certainly not doing it right.

    So the question is: what is the correct way of loading the modules and using their properties and functions - through the class or interface and how it's done? Please set up a small code example so I can get the concept of base as well as the readers of this thread.

    Thank you!!!

    (3) again, you will need to use a shared interface or a common base class.

    Most people put the UI widgets in a module and they all extends UIComponent

    You can reference them as UIComponents.  If they need to access other

    Properties and methods, they define an interface.

    (1) my guess is that the button does not know what a module with embedded

    fonts loaded and don't refresh to use.  Normally, you would

    wrap styles in the module with the fonts, and then set styleonce

    the module is loaded.  In this case, you specify MyriadPro as the

    CSS font family and he would set via setStyle once the module is loaded.
